Puella Magi Madoka Magica

Sayaka  :   What do I even care anymore? Who do I want to protect? 
            I don't even know anymore.

Kyoko   :   Hey...

Sayaka  :   The balance between hope and despair is always zero. 
            You said so yourself. I understand what you meant now.
            I've saved plenty of people. But in exchange, resentment
            and pain took root in my own heart. I'm even hurting my
            dearest friend now.

Kyoko   :   Sayaka! Are you?!

Sayaka  :   As much as I wished for the happiness of one... 
            Someone must be equally cursed. That's how the story
            of a magical girl goes... I've been such a fool.
